Specification of Letters Patent.

Patented Feb. 3,1914.

To all whom it may concern: 7

Be it known that 1, JOHN S. SURBAUGH, a citizen of the United States,residing at Vincennes, in the county of Knox and State of Indiana, haveinvented certain new and useful Improvements in Shovels, of which thefollowing is a specification.

This invention relates to grain andcoal shovels of the hollow back type;and the object of the invention consists in the provision of shovels ofthe above character which will be simple in construction, light inweight, strong, durable and cheap to manufacture.

I accomplish the above objects of the invention by means of thestructure shown in the accompanying drawings, forming a part hereof, inwhich- Figure 1 is atop or plan view of a blank, comprising a unitstructure as it is cut by the die from the metal sheet. Fig. 2 is a topor plan view of a finished shovel showing the ribs for reinforcing theshovel blade extending upwardly into the flanged portion of the shovelblade. Fig. 3 is a view similar to Fig. 2 except that the rear ends ofthe ribs for reinforcing the shovel are bent toward the handle to addgreater strength to the shovel blades. Fig. 4 is a view similar to Fig.2 except that the rear edge of the shovel blade is formed in a curl toadd still greater strength and rigidity to the shovel blade. Fig. 5 isan enlarged detail sectional view on the line 55 in Fig. 4.

Referring to the drawings, 10 represents the blank which is cut from thebody of the sheet metal by means of a suitable die in the usual manner,and terminates in the shank member 11., The blank 10 is placed into acrimping machine in which the shovel blade is formed, whereby thesurrounding edges of the blank are raised to form the flanges 12, 12 and13. The shank 11 is then bent into a cylinder to form a socket forsecuring the well known wooden handle. The flanges 12, 12 and 13 risingabove the flat portion of the blade form a pocket for holding thematerial, this being common to all shovels. The flat portion of theshovel or blank is provided with a tapering frog 14, which is crimpedupwardly, and which extends backwardly and merges with the shank 11,forming a socket for the handle, as shown in Fig. 2 of the drawings. Thefrog 14 adds rigidity to the shovel blade and is enerally regardedsuflicient in handling lig 1t material. For the handling of heaviermaterial the shovel is provided with the ribs 16, as shown in Fig. 2,wherein the ribs extend backwardly from the meetin point 16 of the rearflange 13 with the blade of the shovel. Fig. 3 shows that portion of theribs 16, which extend across the face of the flange 13, being formed atan angle so that their rear extremities terminate in or near the centralfrog 14, thus insuring greater torsional support to the handle socket.It will be noted that the ribs above noted have their greatest width atthe meeting point 16 of the flange l3 and the blade portion of theshovel and that they taper gradually toward their extremities, as shown,which construction gives the greatest strength at the point ofgreateststrain, through the crystallization of the material along the line 16The main object of this invention is to remedy this difficulty byincreasing the strength and rigidity of the shovel blade, withoutincreasing the weight, by providing the ribs heretofore described. Theshovel blades may be further strengthened by curling the rear edge ofthe flange 13 into a roll or bead 20, which roll, if desired, may extendacross the back and around the sides toward the cutting edges of theblades. The formation of the roll 20 is best shown in the enlargedsectional view illustrated in Fig. 5.

Having thus fully described my said invent-ion, what I desire to secureby Letters Patent, is-

1. A shovel blade comprising a unit blank provided with an integralshank, said blank being crimped to provide a flat portion with raisedsides and back, a cylinder formed of said shank, a centrally formedreinforcing frog in said blade extending to and merging with saidcylinder, a reinforcing rib formed on each side of said frog across thejuncture of the back and flat portion of the shovel blade and havingtheir greatest width at said juncture, the rearward ends of said ribsback of said juncture being turned inwardly toward the central frog.

2. A shovel blade comprising a unit blank provided with an integralshank, said blank being crimped to provide a flat portion with raisedsides and back, a cylinder formed of said shank, a centrally formedreinforcing frog in said blade extending to and merging with saidcylinder, a reinforcing rib formed on each side of said frog across thejuncture of the back and fiat portion of the shovel blade and havingtheir greatest width at said juncture.

3. A shovel blade comprising a unit blank provided with an integralshank, said blank being criinped to provide a flat portion with raisedsides and back, a cylinder formed of said shank, a centrally formedreinforcing frog in said blade extending to and merging with saidcylinder, a reinforcing rib formed in said blade on each side of saidfrog the rear end of which terminates near a curl on the rear end of theshovel, said curl extending to and merging with the base 15 of thecylinder.

In witnesses whereof, I, have hereunto set my hand and seal atVineennes, Indiana, this 15th day of June, A. D. one thousand ninehundred and twelve.
